Based on the high binding affinity between biotin-streptavidin systems, our Streptavidin series products are recommended to use together with biotinylated proteins to get lower non-specific binding results in a shorter time.
This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 42.2 kDa. The protein migrates as 55-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Please see Certificate of Analysis for specific instructions.
For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
Biotinylated Human CD47, Fc,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
Immobilized Human SIRP alpha, His Tag (HPLC-verified) (Cat. No. SIA-H5225) at 2 μg/mL (100 μL/well) can bind Biotinylated Human CD47, Fc,Avitag (Cat. No. CD7-H82F6) with a linear range of 0.004-0.06 μg/mL (QC tested).
Immobilized Biotinylated Human CD47, Fc,Avitag (Cat. No. CD7-H82F6) at 1 μg/mL (100 μL/well) on streptavidin precoated (0.2 μg/well) plate, can bind Cynomolgus SIRP alpha, His Tag (Cat. No. SIA-C52H7) with a linear range of 0.039-0.625 μg/mL (Routinely tested).
Serial dilutions of Anti-Human CD47 Neutralizing Antibody were added into Human SIRP alpha, Mouse IgG1 Fc Tag (HPLC-verified) (Cat. No. SIA-H52A8): Biotinylated Human CD47, Fc,Avitag (Cat. No. CD7-H82F6) binding reactions. The half maximal inhibitory concentration (IC50) is 0.2006 μg/mL (Routinely tested).
Serial dilutions of Anti-Human CD47 Neutralizing Antibody were added into Human SIRP alpha, His Tag (HPLC-verified) (Cat. No. SIA-H5225): Biotinylated Human CD47, Fc,Avitag (Cat. No. CD7-H82F6) binding reactions. The half maximal inhibitory concentration (IC50) is 0.1245 μg/mL (Routinely tested).
FACS assay shows that Biotinylated Human CD47, Fc,Avitag (Cat. No. CD7-H82F6) can bind to ACHN cell expressing human SIRP-a. The concentration of CD47 used is 3 μg/mL (Routinely tested).
FACS analysis shows that the binding of Biotinylated Human CD47, Fc,Avitag to ACHN expressing SIRP-a was inhibited by increasing concentration of neutralizing SIRP-a antibody. The concentration of Human CD47 used is 3 μg/mL (Routinely tested).
